\ Ei'generally indicates the carriage structure which ismounted forexample upon thefcylindrical supporting track and is held against rotation in relation thereto, for exa-l'nple bythe rectangular track which is engaged by the adjustable contact'members E in the arms E which proj ect downwardly frolnj'the carriage E. It will be understood that the tracks E E serve to guide the car} rifage along a path or excursion. substantially parallel with the faces of the gua'rdplateiC and the gauge plate D. V 1 V In the form of inyfidevice herein showna ineat on work support generally indicated as G is pivotally mounted upon the carriage E,

as at G1. Referring tothe support whenit is inthe positionin which it is shown in Figure 1', it includes a horizontal work supporting a A gaging r work thrustingflange G3; In order to permit the device to be tilted in relation 'to the' car- PAT NT,[or 'cE ri'age in order to convert thesupportintoa V trough, I provide links Gipivoted as at G and slotted as at G? toreceive thelocking knob GT mounted upon the carriage E.

Associated with the work support is the i U hollow-guide rod Hlthe forward end ofwhich may be 'monntedwfor example in the memberv H associated with the'upstandingelement or flange G3, Concentricwiththe rod H, and Surrounding it, is the sleeve H the sleeve'being slidable upon the exterior of therod. Po sitioned within the hollow of the'rod H is 'a spring H? one endo'f which is secured-as at i 4 Hf, in relation tot-he and H a-nd atabutment'Hl. v The other is secured to acapI-IF' which may be screwthreaded into the end of. the rod H and which moves with it andis efi'e'ctively unitary with it. The'cap H is flange H" of till greater diameter than the cylindrical exterior of the rod H The spring H serves normally to hold the sleeve H in the position in which it is shown in Figure 2, the inner end of the sleeve H abutting against the member H. H is a guard plate secured to the member H and flange G Slidable along the cylindrical exterior of the sleeve H is an outer sleeve J. The sleeve J is adapted to serve as a manual handle for the movement of the carriage E along the tracks E E Extending therefrom and over the flange G is the extension J which may form a unit with the manual handle J 2 which in turn connects with the sleeve J 3 through which passes the pin J 4 at the outer end of which is mounted any suitable pusher plate J whereby the work hay be thrust across the face of the support G and against the gauge plate D. The pin J 4 may be screwthreaded and may have associated with it looking and adjusting nuts J whereby the position of the pusher plate J 5 in relation to the handle J 2 may be varied. In the form of my device herein shown the pusher plate is provided at each end of its lower edge with a downward projection J 7 in which may be mounted an anti-frictional member J 8 adapted to engage the upper surface of the member G In the normal operation of my device it will be understood that, when the pusher plate is in employment, it may be drawn rearwardly to permit the work to be positioned upon the support G This retrograde manual movement of the pusher plate draws the sleeve J against the flange H of the plug H and moves the sleeve H rearwardly upon the sleeve H, against the spring H which tends tensionallv to resist this movement. When the work has been positioned and this manual pressure is released, the spring I-I urges the sleeve H toward the cuttingplane, and thereby moves the sleeve J and thus moves the pusher plate J 5 against the work, urging the work against the gauge plate D. This yielding thrust continues until the forward end of the sleeve I-I engages the member H Thereafter the operator must manually thrust the pusher plate, which he may do by grasping either the sleeve J or the handle J In practice a convenient method is for the operator to place his fingers about the sleeve J, his fingers also abutting against the member J He may then exercise'a slanting thrust, which serves 7 at the same time to move the carriage for the cutting stroke, and to thrust the pusher plate against the work, and the work against the guage plate.

It will be understood that the employment of the extensible guide above described for the sleeve J not only provides a yielding thrust for part of the excursion of the pusher plate, but permits the pusher plate to be employed with work which extends rearwardly from the gauge plate for the entire length of the member Gr of the support G". In efi'ect, extensible guiding means are employed for the sleeve J, ample to make the pusher plate usable throughout the entire length of the carriage or support.

The operator may prefer to dispense with the'pusher plate, in which case he may withdraw the pusher plate to the position in which it is shown in Figure 4, enabling it to clear the support G The pusher plate may then be rotated into the dotted line position in which it is shown in Figures 1 and 3. It will be understood that the sleeve J, and with it the handle J 2 is rotatable about the sleeve or guide H and the pusher plate itself is rotatable in relation to the sleeve H Therefore the pusher plate will easily be rotated into the dotted line position of Figures 1 and 3. The operator may then release the pusher plate and permit the spring H to contract. This contraction of the spring will hold the parts in the position in which they are shown in dotted line in Figure 3. In order to hold the pusher plate fixed in inoperative position, I may employ the guide or support K, as shown in Figures 3 and 4, with its outwardly extending horizontal portion K upon which the lower edge of the pusher plate J 5 may be supported. The engagement of the handle J 2 or the connecting member J with the edge of the support G serves as a limit or step. In order to limit the outward movement of the sleeve H in relation to the sleeve H, I may employ the stop K which slides in a slot K in the sleeve H and is itself fixed upon the inner surface of the forward end of the sleeve H It will be realized that whereas I have described and shown a practical and operative device, nevertheless many changes might be made in the size, shape, number and disposition of parts without departing from the spirit of my invention. I therefore wish my description and drawings to be taken as in a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing.

The use and operation of my invention are as follows:

In a slicing machine of the type herein shown it is sometimes desirable, and in fact frequently desirable, to employ a pusher plate for thrusting the work toward the cutting plane, and against the gauge plate. 1 provide a pusher plate which is effective throughout the entire length of the support G and which, initially, provides a yielding thrust, which is supplemented, as to the last few inches, by a manual thrust, effective after the engagement of the parts terminates the yielding thrust. When the operator wishes an unimpeded upper surface, as in decrusting bread, or when he is slicing materials which he wishes to hold manually, he can dispense with the pusher plate by withv and means for guiding it past the cutting edge of the knife, a pusherplate mounted drawin it and rotating it in inoperative position. t will there remain, yieldingly held in inoperative. position, as shown in dotted line in Figure 3.
